The oft-reliable KGI Securities analyst Ming-Chi Kuo claims that next year, Apple could be planning on releasing a sixth-generation iPad offering between 30 and 40 percent higher pixel density in its 9.7-inch display.
Ming-Chi Kuo's postulation comes following reports arguing that this year's iPad offering could see a 12.9-inch iteration reach Apple Store shelves. This would mean that consumers would be able to choose from a 12.9-inch "iPad maxi," a 9.7-inch iPad, and a 7.9-inch iPad mini.
Kuo, however, disagrees. In a new research note that reached us from MacRumors, the analyst rather argues that next year's iPad 6 could offer users "more competent visuals" through increasing the tablet's pixel density by between 30 and 40 percent.
He explains:

Contrary to speculation that next year’s iPad next year may come in a 12” form, or larger, we think it will not change from the current 9.7” format as we think a 12” iPad would not provide a good mobility experience given today’s technology limitations.
In light [of] advancing Oxide and a-Si technologies, the PPI of iPad 6, which we expect to come out at end-2014, will exceed that of 2013’s iPad 5 by 30-40%, which will offer more competent visuals.
